Agalsidase alfa is used as a long-term enzyme replacement therapy in individuals with Fabry disease (a rare inherited disorder where the body lacks a certain enzyme, resulting in the build-up of a certain type of fat called globotriaosylceramide in the cells of the body).
Agalsidase alfa injection is to be given intravenously (into the vein) as an infusion. It is delivered directly into the bloodstream via the blood vessel.
Your doctor or nurse will administer the injection for you.
Ensure that you keep all appointments with your doctor so that you do not miss any doses. Your doctor also needs to regularly monitor your response to Agalsidase alfa.
If you miss an appointment or miss an injection, alert your doctor or nurse. A replacement appointment or injection should be given as soon as possible.
